Normally we will face some problem with datetime control in any application because of local datetime formats. It will differ for each user how they have configured in the local computer. Now i am giving a generic solution for any type of datetime formats in the local system.
string date=System.DateTime.Now.ToString();
CultureInfo info = new CultureInfo(System.Threading.Thread.CurrentThread.CurrentCulture.ToString());
info.DateTimeFormat.ShortDatePattern = "MM/dd/yyyy";
System.Threading.Thread.CurrentThread.CurrentCulture = info;
Response.Write(Convert.ToDateTime(date));
